## integration

*noun* *(Concise Encyclopedia)*

In calculus, the process of finding a function whose derivative is a given function. The term, sometimes used interchangeably with “antidifferentiation,” is indicated symbolically with the integral sign . (The differential *d**x* usually follows to indicate *x* as the variable.) The basic rules of integration are: (1) (*f* + *g*)*d**x* = *f**d**x* + *g**d**x* (where *f* and *g* are functions of the variable *x*), (2) *k**f**d**x* = *k**f**d**x* (*k* is a constant), and (3) (*C* is a constant). Note that any constant value may be added onto an indefinite integral without changing its derivative. Thus, the indefinite integral of 2*x* is *x*^{2} + *C*, where *C* can be any real number. A definite integral is an indefinite integral evaluated over an interval. The result is not affected by the choice for the value of *C*. *See also* differentiation.
